Is it fine to use these forms to ask "what are you making?" or is there a more appropriate way to ask/better verb to use?

I am doing a writing challenge titled "its not my fault" where there was a translation required of "and my students are very creative"  My response of "et mes étudiants peuvent ..." had "étudiants" crossed out and replaced with "élèves". I would appreciate knowing the rationale for this please?
